# Description

Use the exp1 function to obtain a power of e minus 1, e^ number - 1. This is the inverse function of ln1, that is exp1(ln1(x)) = x and ln1(exp1(x)) = x for any number x.

The transcendental number e appears in many mathematical formulas.

If a math operation on finite inputs produces a non-finite output, an execution error is thrown. See math operations for more information.
